Meini Llwydion Group of Standing Stones is a prehistoric standing stone monument located in Wales and protected by Cadw under reference CM054. The site forms part of the broader tradition of megalithic stone erection that flourished across Britain and Ireland during the Neolithic and Bronze Age periods. Standing stones of this type served purposes that remain incompletely understood, though they frequently marked territorial boundaries, ritual sites or the graves of significant individuals within their communities.
The monument rises from bedrock composed of Llanvirn Rocks, an undifferentiated formation of mudstone, siltstone and sandstone laid down during the Whiterock period of the Ordovician geological epoch. This solid foundation would have provided a stable base for the erection and maintenance of the standing stones, though the builders would have needed to exploit natural fractures or quarry suitable stone from accessible outcrops nearby. The local geology thus shaped both the physical character of the monument and the practical constraints faced by its Neolithic or Bronze Age constructors.
The stones that survive today represent only part of what may once have been a more extensive grouping, as is common among standing stone monuments across Wales. The Meini Llwydion Group retains considerable significance as evidence of prehistoric ritual practice and social organisation in this Welsh landscape, and remains a valuable archaeological resource protected for future study and public engagement.
